Title: Light-emitting device
Inventor: YAMAZAKI SHUNPEI
IPC: H01L51/00
Filed: 2021-04-27
Abstract: Provided is a light-emitting element with high external quantum efficiency. The light-emitting element includes a light-emitting layer containing a guest, an n-type host, and a p-type host between a pair of electrodes. A value obtained by subtracting the energy difference between the triplet excited state and the ground state of the n-type host (or the p-type host) from the energy difference between the triplet excited state and the ground state of the guest is 0.15 electron volt or more. Since the light-emitting element is unlikely to cause a transition from the guest in the triplet excited state to the triplet excited state of the n-type host (or the p-type host), the light emission from the guest in the triplet excited state is efficiently performed. Alternatively, in the light-emitting element, the LUMO level of the n-type host is higher than the LUMO level of the guest by 0.1 electron volt or more, or the HOMO level of the p-type host is lower than the HOMO level of the guest by 0.1 electron volt or more. The light-emitting element allows efficient electron-hole recombination in the guest and therefore can increase the luminous efficiency or external quantum efficiency.
